IMPROVEMENT IN PILL-MAKING MACHINES.

Specification forming part of Letters Patent No. [4,l6l. dated June 29,1856.

To all whom it may concern:

Be it known. that I, NOAH W. KUMLER, of the city of Cincinnati, in thecounty of Hamilton and State of Ohio, have-invented a new and usefulImprovement in a Machine for Makiug Pills; and I do hereby declare thatthe following is a full andfexact description-thereof, reference beinghad to the accompanying drawings, forming part of this specification,and to the letters and figures of reference -marked thereon, similarletters and figures referring to correspondingparts of the improvement.

- The nature of my improvement consistsin placing plates of wood ormetal the required distance'apart, and have all or part of themadjustable by means of set-screws, or otherwise, and witha pulley'andbelt draw the pill material between said plates'and roll it out to anyrequired size in the shape of round bars, after which it is conducted toarevolving metal roller provided with semicircular groovescut around itscircumference, and the bars of pill material are carried between theface of said roller and a segmental plate of metal furnished withsemicircular grooves similar to those on the. face of the roller, andthe projections formed by the grooves on the roller andsegmental platecut the bars of pill material into the required sizes, when they arerolledaround bythe motion given to the roller until formed into balls.suitable for use, after which they are discharged from the machine;ready for packing.

To enable othersskilled in the art to make and use my improvement, Iwill proceed 'to describe its construction and operation, by referringto the. accompanying drawings, of which-.- A

FigureA represents a longitudinal sectional elevation of the improvedmachine, showing the manner of placing the pill material in the machineand the manner of rolling and forming thesame into pills. Fig. Brepresents a top view of the machine. Fig. 0 represents the groovedroller drawn separate, in combination with a sectional view of thesegmental grooved plate. Fig. D represents a front elevation of themachine.

1 represents the pulley, provided with acrank, 21, and belt or apron 22, which runs around the drum 3 at the rear end of the machine. The saiddrum revolves in the levers roller.

28 28, for the purpose of tightening the belt, by forcing the drum outwith the set-screws 27 27 on each side of the machine, as shown 17between the grooved roller-12 and segmental plate 14, where it is cut,as before stated, into the proper-sized pieces and rolled into balls.

and finally discharged from the machine at the lower part of thesegmentalplates 14; on the discharging-plate19, as represented in Fig.A.

The roller 12 receives its motionthrough the gear-wheels 16 16, one ofwhich is placed on the axis of the pulley l, and the other on the Thepulley and roller. revolve in the frame 6 6, and 11 represents the rearportion of the frame to which theplates and drum 3 are attached.

9 9 represent adjusting-screws working-in the cross-bars 22 22, for thepurpose of adj ust; i ng the plate 7 7 to'and from the belt 2, and

10 10 are similar screws for adjusting the plate 8 8. The plates 4 and 5are made stationary by attaching them to the frame-piecesd and 11.

18 is what I denominatea powder-box, which receives a vibratory verticalmotion by means-of the levers 25 25, which are attached to the said boxand work'on pivots screwedin the frame, said leversreceiving theirmotion by the cam form of the axis of the shaft, as seen at 26 in Fig.A, at the center of the pulley. The object of this arrangement is to jarsome.

suitable powder downthe couducting'plate 29 upon the roller 12, topreventthe pill material from adhereing to the roller and segmentalplate 14:, and also serves to give a coating to the. ills.

20 20 represent rods made to pass through the framing 6 6 and flanges 1515, for the pur-- pose of holding thegrooved segmental plate 14 v at theproper relative distance fromv the roller 12. Said flanges are part ofthe-segmental plate.

p '13 13, in Fig. 0, represent the'groorescut in the roller, and-14 a.sectional view'of the segmental plate,.which shows the manner of formingthe pill when they are brought together, giving it a. true sphericalshape.

' What I claim as my improvement and desire to secure by Letters Patent,is-

The combination of the adjustable plates 7 and 8, apron 2, pulleyl, anddrum 3, and these in ombination with the grooved roller 12 and segmentalplate 14, all substantially as and for the purposes set forth in theforegoing speei- .fication, and represented iii the accompanyingdrawings.
